Influences to be considered as coefficients during the planning of the reconstruction.

Tissue distension	1–18
Meshes	0.1–1.44
Sutures, Securestrap®	0.4–0.6
Absorbatack®, Glubran®, Tisseel®	0.15–0.3
Position in the abdominal wall	0.9–1
Peritoneum closure factor	4

Please note that the values are derived with the bench test described above from about 200 different reconstructions, which were selected from about 4,500 possibilities. The mesh position was investigated with the same meshes and gave slightly different gripping coefficients so far. The fixation coefficients were calculated per suture knot loop, per tack, per fixation point or per gluing area of half a square centimeter. For the individual surgical unit, the material preferentially used should be tested before coefficients are applied (3).
